Device with movable buttons or switches

ABSTRACT

A surgical device comprising: (a) one or more functional elements, and (b) a selector assembly including: (i) one or more activation buttons, (ii) one or more circuit board switches, and (iii) a shuttle in communication with the circuit board switches or the one or more activation buttons to move the circuit board switches or the activation buttons between at least a first position and a second position so that the circuit board switches or the activation buttons are moveable relative to each other; wherein the one or more functional elements provide a first function when the circuit board switches or the one or more activation buttons are in the first position, and the one or more functional elements provide a second function when the circuit board switches or the one or more activation buttons are in the second position.

FIELD

The present teachings generally relate to devices, more specificallysurgical devices that include a circuit board switch and/or buttons thatare repositionable between two or more positions so that two or morefunctional states are enabled.

BACKGROUND

Typically, surgical devices have one functional element, thus if adifferent function is desired a surgeon will switch devices during aprocedure to a device with a different function. However, some devicesinclude a second functional element and each functional element isactivated by actuating each individual button. For example, if thesurgeon selects a device that has two buttons, one button activatesmonopolar cut and a second button activates bipolar coagulation, thedevice can only provide these functions. Thus, if bipolar cutting isdesired the surgeon either may use bipolar coagulation for a longerperiod of time or the monopolar cutting for cutting or the surgeon canswitch to a device that provides bipolar cutting. This may result inlonger surgery times or a less than optional cut being performed.Further, switching devices in the middle of a procedure may result inthe surgeon losing concentration, losing a feature of interest,extending surgery times, or a combination thereof.

Examples of some electrosurgical instruments may be found in U.S. Pat.Nos. 6,110,171; 6,113,596; 6,190,386; 6,358,268; and 7,232,440; and U.S.Patent Application Publication Nos. 2005/0113827; 2005/0187512;2006/0084973; 2012/0123405; 2014/0276795; and 2014/0276799 all of whichare incorporated by reference herein for all purposes. What is needed isa device that easily transforms between a plurality of differentelectrical states and functions. It would be attractive to have a devicethat can switch between two or more states and multiple states with asingle button. It would be attractive to have a device that mechanicallyreconfigures states so that the circuitry of the device physicallychanges position, electrically reconfiguring the device relative to thebuttons. The buttons would control the functional output of the device.What is needed is a device that can change states so that each buttoncan provide multiple functions.

In another example, one or more parts ofthe device may include a sharp edge and may be used to cut, similar tothat of a scalpel. The surgical device may include a handpiece and agenerator. The surgical device may have one or more therapy signals thatextend between the handpiece and the generator.

The surgical device has a body. The body may function to connect afunctional element to a user interface. The body may provide power,signals, or both to the function element. The body and one or morefunctional elements may be one integral piece or the functional elementmay be removable from the body. The body may include a power source orbe connected to a power source. The body of the device may house thecomponents that are used to make the device functional. The body of thedevice can be a hand piece. The body of the device can be forceps.

The body of thedevice may include or be connected to one or more activation buttons, atleast one circuit board, a shuttle, the functional element, selectorassembly, or a combination thereof.

The selector assembly allows the user to change between a plurality offunctions of the surgical device. The selector assembly may function tochange between multiple functions for each of the one or more activationbuttons. The selector assembly changes the function of the one or moreactivation buttons by moving the one or more activation buttons, thecircuit board, or both. The selector assembly is changeable between twoor more positions so that each of the one or more activation buttonsprovide two or more functions. For example, the surgical device mayperform or provide more functions than activation buttons are present onthe device (e.g., one button may activate 2 or more, 3 or more, 4 ormore, or even 5 or more functions). The selector assembly maylongitudinally move along the surgical device (e.g., may move along inthe direction of the longitudinal axis of the device (e.g., forceps,motorized device, ultrasonic device)); rotationally move around acomponent of the surgical device (e.g., the selector assembly may followthe contour of the surgical device in a direction substantiallyperpendicular to the longitudinal axis); the selector assembly maylaterally move (e.g., from side to side without following the contour ofthe device); or a combination thereof. The longitudinal axis asdiscussed herein is the dimension with the longest length. The selectorassembly may move along or within one or more channels. The selectorassembly may be moveable by a sliding action, a leaf spring mechanism, ashort throw lever assembly, a rack and pinion assembly, or a combinationthereof. The selector assembly may include a portion that is located ona surface of the surgical device and a portion that extends into thesurgical device. The selector assembly may change position through theuse of a position change button. The position change button may be incommunication with a mechanism or assembly that may allow for theselector assembly to move between positions when depressed. The selectorassembly may be on the body, removeably attached to a body, movablealong the body, or a combination thereof. The selector assembly mayinclude the shuttle, the one or more activation buttons, the circuitboard, a position change button, a leaf spring mechanism, a short throwlever assembly, a rack and pinion assembly, or a combination thereof.

The device (e.g., a surgical device) includes a moveable shuttle. Theshuttle may be moveable relative to the body of the surgical device. Theshuttle may move the device between a plurality of states (e.g.,electrical states). For example, the device may be moved from a firststate to a second state. The device may be moved between a first state,second state, third state, fourth state, or more states. The shuttle maymove along a line or axis of the device; along a surface of the device;pivot as a lever on the device; rotate as a knob on the device; or acombination thereof. The shuttle may move between positions (e.g.,first, second, third, or fourth positions) as the shuttle moves alongthe device. The shuttle may longitudinally move along the surgicaldevice (e.g., may move in the direction of the longitudinal axis of thedevice); rotationally move around a component of the surgical device(e.g., may follow the contour of the surgical device in a directionsubstantially perpendicular to the longitudinal axis); the shuttle maylaterally move (e.g., from side to side without following the contour ofthe device); or a combination thereof. The shuttle may move along thelongitudinal axis of the surgical device. The shuttle may move in adirection substantially perpendicular to the longitudinal axis (i.e.,laterally). The shuttle may move around a rotational axis that issubstantially parallel to the longitudinal axis (i.e., rotationally).The shuttle may include one or more of a leaf spring mechanism, a shortthrow lever assembly, or a rack and pinion assembly that assist inmoving the shuttle. The shuttle may be in communication with the one ormore activation buttons, the one or more circuit boards, or both. Whenthe shuttle is in communication with the one or more activation buttons,the one or more circuit boards are stationary relative to the body. Whenthe shuttle is in communication with the one or more circuit boards, theone or more activation buttons are stationary relative to the body ofthe surgical device. When the shuttle is in communication with eitherthe one or more circuit boards or the one or more activation buttons,the one or more activation buttons and the one or more circuit boardsmay move relative to each other. The shuttle may have two or morepositions (e.g., at least a first position and a second position). Theshuttle may have a plurality of positions. The shuttle may have a firstposition, second position, third position, fourth position, or more. Theshuttle in one or more of the positions discussed herein may disable oneor more of the states herein. The shuttle in a first position maydisable a second electrical state, in a second position may disable afirst electrical state and/or a third electrical state, or a combinationthereof. For example, the shuttle in the second position may bepositioned so that the first electrical state is disabled. The shuttlehelps convert the surgical device between states based on the shuttle'sposition. For example, the shuttle in the first position will place thesurgical device in the first state and when the shuttle is moved intothe second position, the surgical device will be converted to the secondstate. The shuttle in a first position may align one or more activationbuttons with one or more circuit board switches, one or more circuitboard switches on a second circuit board, or both. The shuttle in afirst position may misalign the one or more activation buttons with thefirst circuit board switches and align the activation buttons with thesecond circuit board switches, or vice versa. Alignment as discussedherein is when the button is located so that the button can move intocontact with a switch and preferably is when the button can movelinearly and substantially perpendicularly to the switch so that theswitch is activated upon movement of the button. Misalignment asdiscussed herein is where the button when activated upon does notcontact a switch causing an activation of that switch. The shuttle inthe second position may align one or more of the activation buttons withone or more of the circuit board switches, one or more second circuitboard switches, or both. The shuttle may be placed in two or morepositions so that the one or more activation buttons align with ormisalign with the one or more circuit board switches.

The position change button may function to convert the device betweentwo or more positions. The position change button may be incommunication with a mechanism or assembly to convert the device betweenpositions (e.g., from a first position to a second position). Theposition change button when actuated may engage a mechanism or assemblyto move the selector assembly from one position to another position bymoving the shuttle, the circuit board, the activation buttons, or acombination thereof by converting mechanical potential energy intodirectional movement. The position change button is located on theexterior of the device. The position change button may include anactuator. The position change button may act upon a leaf springmechanism, a short throw lever assembly, a rack and pinion assembly, ora combination thereof.

The leaf spring mechanism may convert the device between states (e.g., afirst state and a second state). The leaf spring mechanism may include aposition change button, an actuator block with a track, a plunger, aleaf spring, or a combination thereof. The actuator block may attach tothe circuit board, shuttle, activation buttons, or a combinationthereof. The actuator block may have a track. The actuator block trackmay be on the interior, exterior, or both of the handpiece. The actuatorblock track may have at least one position. The position change buttonmay be used to convert the leaf spring mechanism between positions. Theposition change button may include a plunger. The plunger may fit intothe track of the actuator block. When the position change button isacted upon, the position change button plunger may move between two ormore positions of the actuator block. When the position change buttonplunger moves, the actuator block may change position so that the leafspring can push the actuator block, which is connected to the shuttle,the activation buttons, the circuit board, or a combination thereof. Theforce of the leaf spring expanding may be converted into directionalmovement, moving the device into another position. When the actuatorblock is moved from one position to another position, the circuit board,the shuttle, the one or more activation buttons, or combination thereofmay be moved relative to each other through the transformation of thepotential energy stored in the leaf spring into directional movement.

The short throw lever assembly may be used to convert the device betweena plurality of states (e.g., a first state and a second state). Theshort throw lever assembly when actuated may change the position of theselector assembly from one position to another. The short throw leverassembly may include a lever, a fixed pivot point, one or more movingpivot points, or a combination thereof. The lever may attach to theshuttle, the circuit board, the activation buttons, or a combinationthereof at one of the one or more moving pivot points. The lever maypivot about a fixed point. When a force is put onto the lever, the levermay pivot around the fixed point pushing or pulling the circuit board,the shuttle, the activation buttons, or a combination thereof. The shortthrow lever assembly may move the activation buttons and circuit boardinto alignment or misalignment. The short throw lever assembly may movethe selector assembly by moving the circuit board, the shuttle, the oneor more activation buttons, or a combination thereof relative to eachother, converting the device from one state to another state.

The rack and pinion assembly may be used to convert the device between afirst state and a second state. The rack and pinion assembly may assistin changing the position of the selector assembly from one position toanother position. The rack and pinion assembly may include a piniongear, and one or more rack gears. The rack and pinion assembly may movethe selector assembly through rotating a pinion gear in communicationwith one or more of the rack gears connected with the activationbuttons, the shuttle, the circuit board, or a combination thereof. Whenthe assembly is rotated, the teeth of the pinion gear intertwine withthe teeth of the rack, which may be connected to the circuit board, theactivation buttons, the shuttle, or a combination thereof, moving thecircuit board and the activation buttons into alignment or misalignmentwith one another.

The one or more activation buttons may function to active or deactivatethe functional elements. The one or more activation buttons may actuateone or more circuit board switches, align with one or more circuit boardswitches, or both. The one or more activation buttons may be a pluralityof activation buttons. The one or more activation buttons may be a firstactivation button, a second activation button, a third activationbutton, a fourth activation button, or more activation buttons.Preferably, each actuation button may actuate one or more circuit boardswitches so that a plurality of functions may be provided by thesurgical device. The one or more activation buttons may contact (e.g.,through direct contact or indirect contact) a circuit board switch(e.g., a dome or membrane) to initiate one or more of the functionalelements. The one or more activation buttons may move substantiallylinearly (e.g., perpendicularly to the switches). Each of the one ormore activation buttons may provide a different function, control adifferent functional element, provide multiple functions through thesame functional element, or a combination thereof. The one or moreactivation buttons may be located on the body of the surgical device, onthe shuttle, or both. The activation button when depressed actuates acircuit board switch so that one or more of the functional elements ofthe surgical device are activated. The circuit board switch is actuatedwhen the activation button is depressed, which completes a circuit andpowers one or more of the functional elements. There may be more thanone activation button present on the surgical device. Preferably thereare a plurality of activation buttons. Preferably the one or more of theactivation buttons may have a plurality of positions. For example, eachof the one or more activation buttons may be moved between a firstposition and a second position. The one or more activation buttons maybe longitudinally moveable along the longitudinal axis of the device,laterally moveable along a secondary dimension of the device (e.g., adirection substantially perpendicular to the longitudinal axis),rotatably moveable about the rotational axis, or a combination thereof.Preferably, the one or more activation buttons will move about thelongitudinal axis. The one or more activation buttons may be static. Theone or more activation buttons may be static relative to the body, tothe shuttle, circuit board, or a combination thereof. The one or moreactivation buttons may be a rigid element, non-conductive element, orboth. The one or more activation buttons may be constrained from motionby guides in the body. The one or more activation buttons when alignedwith the circuit board or circuit board switches (i.e., electrosurgicalswitches) may contact the circuit board or circuit board switches whendepressed, activating one or more functional elements.

The circuit board functions to activate or deactivate one or more of thefunctional elements. The circuit board functions to receive one or moreuser inputs and control one or more functional elements of the surgicaldevice. There may be more than one circuit board in a surgical device.The circuit board may have surface mounted circuitry, through-holecircuitry, or both. Preferably, the circuit board has surface mountedcircuitry. The circuit board may have components mounted or placed ontothe surface. For example, all of the circuit componentry, including thecircuit board switch, are mounted on the top surface of the circuitboard to allow the circuit board to be mounted flat onto the mountingsurface of the device. The circuit board may be of a through-holeconstruction. Through-hole construction fits the components with wireleads into holes in the circuit board. When more than one circuit boardis present the circuit boards may be movable relative to each other. Forexample, one circuit board may be moved over or under another circuitboard so that a different function may be activated. One circuit boardmay be movable and one circuit board may be static. Both circuit boardsmay be movable. Each of the one or more activation buttons may provide adifferent function, control a different functional element, providemultiple functions through the same functional element, or a combinationthereof. The one or more circuit boards may be located on or within thebody of the surgical device, on or within the shuttle, or both. The oneor more circuit boards are used to activate a functional element of thesurgical device. The one or more circuit boards have at least one switchper circuit board that interact with the one or more activation buttons.The circuit board switches may be surface mounted switches. When thecircuit board switch is actuated by the depressed activation button, thecircuit board switch closes a circuit of the circuit board and enablesthe functional element of the surgical device. There may be more thanone circuit board present on the surgical device. The surgical devicemay include a plurality of circuit boards. For example, the surgicaldevice has a first circuit board and a second circuit board. The firstcircuit board, when activated, enables a first functional element andthe second circuit board, when activated, enables a second functionalelement. The surgical device may have one activation button that movesbetween the two circuit boards and aligns with the first circuit boardwhen in the first position and the second circuit board in the secondposition. In the first position, the second circuit is misaligned withthe activation button and in the second position, the first circuitboard is misaligned with activation button. Preferably the one or moreof the circuit boards may have a plurality of position. For example,each of the one or more circuit boards may be moved between a firstposition and a second position. The one or more circuit boards may belongitudinally moveable along the longitudinal axis of the device,laterally moveable along a secondary dimension of the device (e.g.,substantially perpendicular to the longitudinal axis), rotatablymoveable about the rotational axis (e.g., an axis that is parallel tothe longitudinal axis), or a combination thereof. Preferably, the one ormore circuit boards will move about the longitudinal axis. The one ormore circuit boards may be static. The one or more circuit boards may bestatic relative to the body, to the shuttle, the activation buttons, ora combination thereof. There may be more than one circuit board switcheson a circuit board. For example, there may be two circuit board switcheslocated on the same circuit board (e.g., a first circuit board switchand a second circuit board switch). For example, both a first circuitboard and a second circuit board may include a first circuit boardswitch and a second circuit board switch. When the first circuit boardswitch is depressed, a first function is performed and when the secondcircuit board switch is depressed, a second function is performed. Thecircuit board may include one or more switches.

The circuit board switches enable the surgical device to activatefunctional elements through interacting with the circuit board and theone or more activation buttons. Each of the circuit boards may includeone or more switches and preferably a plurality of switches. The one ormore switches may be a first switch, a second switch, a third switch, afourth switch, a fifth switch, or more switches. The device may includethe same number of switches as buttons. For example, the device mayinclude two buttons and two switches. The device may include a differentnumber of buttons and switches. For example, the device may includethree switches and one button. In another example the device may includetwo buttons and three switches. The one or more circuit board switchesmay be flat, convex, concave, a dome switch, a membrane switch, anelectrical switch, a capacitive sensor, a pressure sensor, or acombination thereof. Preferably, the one or more circuit board switchesmay be a dome switch. The one or more circuit board switches interactwith the one or more activation buttons when the one or more activationbuttons are aligned with the circuit board switches such that when theone or more activation buttons are depressed, the buttons make contactwith and engage the one or more circuit board switches to complete thecircuit, enabling a functional element of the surgical device. Thecircuit board switches may be activated without being contacted. Forexample, depression of an activation button may create a field thattriggers the circuit board switch so that a function is activated. Theone or more circuit board switches and the one or more activationbuttons are brought into alignment by changing the position of theselector assembly.

The state (e.g., electrical state or mechanical state) of the surgicaldevice is changeable so that a functional element is activated. Thesurgical device has at least two states. Each of the states provide oneor more different functions. For example, the first state is a forcepsand provides a bipolar therapy current and a second state is a probethat may provide cutting and provides a monopolar therapy current. Thesurgical device creates a first state when the selector assembly is inthe first position. When the selector assembly is in the first position,at least one circuit board switch is aligned with at least one of theactivation buttons so that when the activation button is engaged, theactivation button contacts the circuit board switch on the circuitboard, completing the circuit and enabling a first function.

The second state changes the surgical device (e.g., mechanically orelectrically) into a secondary form to allow a second element of thesurgical device to be used. The second state is created when theselector assembly is in the second position. In the second state theselector assembly is advanced to the second position where the selectorassembly moves either the one or more circuit boards or the one or moreactivation buttons. When the circuit boards or activation buttons aremoved, the previously enabled function is no longer accessible due tothe misalignment or realignment of the activation buttons and thecircuit board switches. In the second state one or more of theactivation buttons may be misaligned with one or more of the circuitboard switches so that the activation button that is misaligned iseffectively disabled. In the second state, the selector assembly is inthe second position so that the activation button and the circuit boardswitch on the circuit board may be misaligned, so when the activationbutton is depressed, the button does not contact the circuit boardswitch and does not enable one or more of the functional elements. Thesecond state of the surgical device may realign one of the activationbuttons with one of the circuit board switches so that a functionalelement is activated, which is different than the functional elementactivated in the first state. In the second state the shuttle is in thesecond position so that at least one of the activation buttons arealigned with another circuit board switch, differing from the alignmentin the first state so when the activation button is depressed, thebutton makes contact with the circuit board switch, enabling a secondfunctional element of the surgical device. For example, if the firstfunctional element produces a therapy current, the second functionalelement may be a different therapy current. The second state of thesurgical device may be a non-powered element.

The one or more functional elements are an integral part of the surgicaldevice or a part that may be added to the surgical device so that thesurgical device may be used to perform a surgical procedure. Thesurgical device has at least one functional element. The functionalelement may be actuated when the circuit is completed by depressing theone or more activation buttons. Preferably, the surgical device has morethan one functional element. For example, the surgical device may beelectrosurgical forceps where in the first state the electrosurgicalforceps produce a therapy current and in the second state the surgicaldevice would function as non-electrical forceps. Preferably, thesurgical device has a plurality of functional elements (e.g., three ormore, four or more, or even five or more). The functional elements maybe electrical, motorized, ultrasonic, mechanical, or a combinationthereof.

When the functional elements are electrical elements the functionalelements use electricity to perform one or more portions of a surgicalprocedure. Electrical elements are functional elements that useelectricity to operate. The electrical element may be an electrode, anelectrical motor, an ultrasonic transducer, or a combination thereof.The first electrical element may be a motor and the second electricalelement may be an electrode. The second electrical element may be anelectrode, a second therapy current, a motor, an ultrasonic transducer,or a combination thereof. Preferably, the second electrical element is asecond therapy current that passes through at least the secondelectrical element. The motor may be operated when an activation buttonis in a first position and the electrode may be activated when theactivation button is in a second position. The surgical device may haveat least one electrical element. The surgical device may have at leasttwo electrical elements. The surgical device may have a plurality ofelectrical elements.

The electrical functional element of the surgical device may include oneor more electrodes. Electrodes conduct electricity through the surgicaldevice upon activation. Electrodes may conduct therapy currents. Atherapy current may be a monopolar current, bipolar current, or acombination thereof. The therapy current may be used to cut, cauterize,coagulate, or a combination thereof during a surgery. The electrodes mayconduct a therapy current that is used to actuate a motor.

The functional element of the surgical device may be a motor. A motorfunctions to move a component of the surgical device. The motor may beelectrically powered, pneumatically powered, hydraulically powered, or acombination thereof. The motor may be used to cut, grind, saw, drill, ora combination thereof. For example, the motorized functional element ofthe surgical device may be a debrider, which has a stationary outerblade and rotating inner blade or the motorized functional element maybe a second functional element such as irrigation or suction. In thefirst functional state, the debrider may be actuated and in the secondfunctional state the irrigation or suction element may be actuated by anopening of a solenoid powered valve impinging on a fluid line. Forexample, the device in a first state may actuate a debrider function tocut a targeted area, and the device in a second state may actuate avacuum source to remove debris and liquid from a targeted area, and in athird state may actuate an irrigation source to provide saline solutionto a targeted area. The vacuum and irrigation may be obtained from apreexisting source and may be actuated by the activation of a solenoid.In another example, the device in a first state activates the debriderfunction and the device in a second state activates a bipolarcoagulation function without activating the debrider motor.

The functional element of the surgical device may be an ultrasoniccomponent. The ultrasonic functional element may be used to identify atargeted area, cut, coagulate, or a combination thereof. It is preferredthat the ultrasonic element cuts and coagulates by converting theelectrical energy to mechanical vibration that is applied to tissue.Ultrasonic capabilities can be combined with a monopolar function, abipolar function, or both. For example, the device in a first state maybe actuated to produce ultrasonic energy to cut a targeted area, and thedevice in a second state may actuate a bipolar therapy current tocoagulate a targeted area. In a further example, the device in the firststate sends ultrasonic energy to a targeted area, and in the secondstate sends both ultrasonic and bipolar energy to a targeted area tosimultaneously cut and coagulate.

The functional element of the surgical device may be mechanical device.A mechanical functional device is substantially free of electricity orany other power source. The mechanical element may be using the surgicaldevice to cut, grip, probe, saw, strike, or a combination thereof.

The surgical device may be a combination device. A combination deviceincorporates two or more structural elements into a single device tomake a tool that is capable of performing multiple functions withoutswitching handsets.

The buttons 26, 28, 30 are connected to actuation devices70, so when the buttons 26, 28, 30 are depressed in the 52 direction,the actuating device 70 depress the respective circuit board switch 42,44, 46.

FIG. 12B illustrates a selector assembly 38, which is shown as akeyboard 62. The circuit board 40 of the keyboard 62 is shown moving inthe 48 direction from a first position 22 to a second position 24. Inthe second position 24 alignment of the circuit board switches 42, 44,46 are changed relative to the first position 22. As shown activationbutton 26 is aligned with circuit board switch 44, activation button 28is aligned with circuit board switch 46 and activation button 30 ismisaligned (i.e., does not align with a circuit board switch). So whenthe activation buttons 26 and 28 are depressed in the 52 direction, theactuation device 70 will contact the circuit board switches 44 and 46.Similarly, Circuit board switch 42 is misaligned and does not align withan activation button and thus this functionality is effectivelyunactuatable.

FIG. 13A illustrates the selector assembly 38 in position one. Theselector assembly 38 is connected to the circuit board 40 through a leafspring mechanism 96. In position one, the activation buttons 26, 28 arecarried on the shuttle 20 and are aligned with the circuit boardswitches 42, 44. When activation buttons 26, 28 are depressed in thedirection 52, the activation button 26, 28 will contact circuit boardswitches 42, 44, respectively. No activation buttons are aligned withcircuit board switch 46. The selector assembly includes a positionchange button 74 which is in communication with the leaf springmechanism 96. The leaf spring mechanism 96 includes an actuator block 98with a track 110, a plunger 108, and a leaf spring 104. The actuatorblock 98 attaches to the circuit board at region 106. The track 110 ofthe actuator block 98 has a top position 100 and a side position 102.The plunger 108 is connected to the position change button 74 and fitsinto the positions of the actuator block 100, 102 so when the positionchange button 74 is acted upon in direction 52, the plunger 108 movesfrom the top position 100 to the side position 102. When the plunger 108moves, the leaf spring 104 can push the actuator block 98, which isconnected to the circuit board 40 at 106, converting the device intoposition two. When the actuator block is moved from position one toposition two, the circuit board 40 is moved relative to the activationbuttons 26, 28. To move the device back to position one, the positionchange button can be actuated, causing the plunger to move about thetrack of the actuator block clockwise so that the plunger returns toposition one.

FIG. 13B illustrates the selector assembly 38 in position two 24. Theselector assembly 38 is connected to the circuit board 40 through a leafspring mechanism 96.

The leaf spring assembly 96converts the device from position one 22 to position two 24 throughactuating the position change button 74 in the direction 52. Theposition change button depresses the plunger 108 causing the leaf springmechanism 96 to relieve tension on the leaf spring 104 which expands andmoves the circuit board 40 laterally by pushing the actuator block 98,which is connected to the circuit board 40 at 106, placing the device inthe second position 24. When the position change button 74 is depressed,the plunger 108 moves along the track 110 of the actuator block 98 fromthe top position 100 to the side position 102. The circuit board 40moves relative to the activation buttons 26, 28. The activation buttons26, 28 are stationary relative the circuit board 40.

FIG. 14 illustrates the selector assembly 38 connected to the circuitboard 40 through a short throw lever assembly 86 where the shuttle 20holds the activation buttons 26, 28 aligns with the circuit boardswitches 42, 44 so that when the activation buttons 26, 28 are depressedin the direction 52, the activation buttons 26, 28 will contact thecircuit board switches 42, 44 respectively. In this position, the thirdcircuit board switch 46 is not aligned with either of the activationbuttons 26, 28. The short throw lever assembly 86 includes a lever 92, afixed pivot point 88 that the lever rotates about, and moving pivotpoints 90 at the circuit board and the shuttle, respectively. The shortthrow lever assembly 86 converts the device between positions when movedin the 94 direction by laterally moving the shuttle 20 holding theactivation buttons 26 and 28 in the 64 direction and the circuit board40 in the 48 direction. The shuttle 20 and the circuit board 40 areconnected by the lever 92 at moving pivot points 90, so when the shortthrow lever assembly 86 is acted upon, the lever 92 pivots about thefixed point 88, moving the shuttle 20, which holds the activationbuttons 26 and 28, and the circuit board 40 into aligned or misaligned.

FIG. 15 illustrates the selector assembly 38 is connected to the circuitboard 40 and shuttle 20 through a rack and pinion assembly 80. The rackand pinion assembly 80 helps convert the device between a first positionand a second position by allowing the shuttle 20, carrying theactivation buttons 26 and 28, to move relative to the circuit board 40.The rack and pinion assembly 80 includes a pinion gear 82 and a pair ofrack gears 84, each attached to the circuit board 40 and the shuttle 20.As the pinion gear 82 rotates, the rack gears 84 laterally move theshuttle 20 in the 64 direction and circuit board 40 in the 48 directionplacing the device into a second position, aligning or misaligning theactivation buttons 26, 28 with the circuit board switches 42, 44, 46. Inthe position shown, the activation buttons 26 and 28 are aligned withcircuit board switches 42 and 44, so when the activation buttons aredepressed in the 52 direction, activation button 26 will contact circuitboard switch 42 and activation button 28 will contact circuit boardswitch 44. Circuit board switch 46 is not aligned with any activationbuttons. A rack and pinion converts rotational movement to longitudinalmovement or lateral movement.
